Guerrero beaches closed from 7PM till 6AM

A notice that just popped up on Facebook say the Governor of Guerrero has ordered all beaches in the state closed as of 7:00 tomorrow night.

It will be from this Tuesday that the beaches will close from 7:00 at night and will be maintained during the New Year's Eve festivities, when many people flock to the beaches of the municipality.

Edited to add...different articles are saying different things, like referring specifically to Acapulco, and one used the term "partially closed".

I believe you misunderstood a bit. Beginning Tuesday, there will be a curfew imposed on the beaches only. No one will be allowed on the beach between the hours of 7:00 PM and 6:00 AM. This is intended to keep folks from celebrating Año Nuevo on the beach and lighting off banned fireworks. After Año Nuevo we should be back to normal.
